SIP Trunks.

SIP Trunks is an IP telephony service that utilises your internet connection

They are ideal for businesses who want to retain an on-site PBX, and route calls over robust IP connections.


This next-generation technology provides a multi-channel VoIP communications line in and out of your premises and connects to any PBX with an IP Telephony gateway. SIP Trunks allow you to easily add extra capacity as and when you need it, and are the go-to option for replacing legacy phone lines with cheaper, more versatile technology.


Offering the stripped down functionality of our Cloud PBX service, Vostron SIP Trunks incorporate your office PBXs with our hosted multi-site service. They are a great way to quickly scale capacity, consolidate billing, and add resilience by using the multiple paths of your Vostron managed internet connection.


Because our SIP Trunks are delivered from within the core of our network, they come with Solid SLAs and a guaranteed service, as well as same-day activation for additional channels. With network-level security, they are the perfect solution for businesses transitioning from a traditional phone line to IP telephony. For older PBXs with no IP capabilities, hybrid solutions are also available.

Cloud PBX.

Easy & Effective Hosted Telephony

With our Cloud PBX service, you get a powerful phone system that is easy to set up and simple to use. Delivered over fully managed connectivity, and with hundreds of features, you can customise it to resolve even the most complex of challenges.


We manage your hardware as part of the service, push out updates, integrate your contact lists, and provide friendly, desk-level support from the same engineers that maintain your connectivity. There’s no clunky equipment or patchy call quality either. Simply plug in your handsets and we’ll take care of the details, so you can focus on running your business.


Built With You In Mind

It’s not a one-size-fits-all solution either. We tailor your Cloud PBX to your individual requirements and can scale your service from 1 to 1,000 handsets.


You get a completely bespoke service that is tailored to your needs, making our Cloud PBX perfect for both small businesses and multi-site operations. In addition to secure communication and proactive management, the service comes with a 100% uptime guarantee – and best of all, it comes with connectivity and network management in a fully managed service.


Whilst some of our customers simply require a fast and effective internet connection, others want to take full advantage of our networking expertise, and extend our support to every desk in their office.

“We decided to go with Vostron as we felt it was important to not have a one-size-fits-all solution. The way Vostron were useful was that they took the time to get to know our business, and before they made a blanket recommendation they were genuinely trying to figure out what we needed from an operational point of view – we got a very tailored solution from them upfront.”
